The differential diagnosis includes neuromuscular disorders i. Femoral deformities can also arise after treatment of hip dysplasia.
Magnetic resonance imaging MRI can be used to illustrate the soft tissues and assess impingement. Views Read Edit View history. The more coxxa and the more chronic a hip deformity, the more likely there are to be associated soft tissue contractures.
Unsourced material may be challenged and removed. Pectus excavatum Pectus carinatum. Literature is lacking, but surgical management appears to be the accepted treatment protocol for this condition. Ashish Ranade et al ocxa showed that a varus position of the neck is believed to prevent hip subluxation vada with femoral lengthening.
The approach is really two osteotomies: A Trendelenburg limp is sometimes associated with unilateral coxa vara and a waddling gait is often seen when bilateral coxa vara is present. There are three approaches to correction of trochanteric overgrowth, each with separate indications:.
The femoral osteotomy should be medially translated towards the inside to avoid a secondary translation deformity. There is less danger to the circulation of the femoral head than with the other two approaches because the dislocation helps avoid injury to the femoral head.
This example demonstrates that hip dysplasia can be corrected with osteotomy of the femur and not a pelvic osteotomy.
The osteotomy is performed and the bone corrected to the desired position. Furthermore, because varus osteotomy shortens the femur this has an effect on the greater ccoxa. Congenital coxa vara results in a decrease in metaphyseal bone as a result of abnormal maturation and ossification of proximal femoral chondrocyte. Acheiropodia Ectromelia Phocomelia Amelia Hemimelia.
Furthermore, the shape of the upper femur is affected by any imbalance of muscle forces around it. A previous pelvic osteotomy had been coda B – Ganz relative neck lengthening and trochanteric transfer Intra-Articular Deformities Intra-articular deformities of the hip are deformities of the femoral head at its connection to the femoral neck.
Coxa vara is usually indicated when the angle is less than degrees. This page was last edited on 1 Aprilat Using the x-rays, the joint orientation angles of the hip are measured. The cpxa is stabilized with blade plate internal fixation.
Deformity of the femur will often cause a resultant deformity in the acetabulum, and a deformity of the acetabulum will cause a valgaa deformity in the femur. Coxa Vara Correction of coxa vara is a valgus osteotomy. Hip, Groin, or Buttock Problem.
CT can be used to determine the degree of femoral anteversion or retroversion. A retrospective study of femoral neck fractures in children show the following complications: Wagner Osteotomy The Wagner osteotomy is used to change the part of the femoral head that is articulating with the acetabulum.
Developmental Coxa Vara
Coxa valga and coxa vara are deformities of the hip. The most serious ones with high and long term morbidity being osteonecrosis and coxa vara. Measuremenst are then taken: Because of this, consideration of the muscles of the hip and vaalga femur is crucial to avoid developing further complications. Protrusio acetabuli Coxa valga Coxa vara. A – Bilateral severe hip dysplasia with elliptical femoral head on right side B – Wagner-type valgus osteotomy performed as well as periacetabular osteotomy PAO of the pelvis.
What makes a synovial joint move smoothly? The effect is to lengthen the femoral neck.
Clinically, the condition presents itself as an abnormal, but painless gait pattern. For more information, see Slipped Capital Femoral Epiphysis. In this case study, the acetabulum is abnormal in coxa vara. Instead, both deformities are caused by the same disease process.
Valgus angles greater than degrees put the patient at risk of hip subluxation dislocation. The hip is well covered, protecting it during lengthening Ganz Osteotomy The Ganz osteotomy is combined with a capsulotomy and a safe-surgical dislocation of the hip.

In the case of acquired coxa vara from a fracture, the proximal femur and femoral neck need accurate reduction and rigid fixation to avoid potential serious complications. A review on the development of coxa vara by Currarino et al showed an association with spondylometaphyseal dysplasia, demonstrating that stimulated corner fractures were present in most instances.
The objective of medical interventions is to restore the neck-shaft angle and realigning the epiphysial plate to decrease shear forces and promote ossification of the femoral neck defect. Macrocephaly Platybasia Craniodiaphyseal dysplasia Dolichocephaly Greig cephalopolysyndactyly syndrome Plagiocephaly Saddle nose. One example is the deformity of the femoral head relative to the neck created by a slipped capital femoral epiphysis can be treated by an intra-articular reduction or osteotomy or an extra-articular reorientation osteotomy.
